X-Git-Tag: firefly_0821_release~9833^2~2834^2~2 X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=b07f6b327e798610bebaa581ffb7a226f3bcb96b;p=firefly-linux-kernel-4.4.55.git sh: Fix up flush_cache_vmap() on SMP. flush_cache_all() uses broadcast IPIs, so we can't wrap in to that when IRQs are disabled. The local cache flush manages to do what we need here anyways, so just switch to that.
